of all the modern and sci-fi systems you know, which one has the best rules for playing as the shooter enemy staple of "beefy guy in riot armor waddling toward you with a giant gun"? Bonus points if it's actually viable as a character and not just a crippling gimmick.
Traveller, get a few million credits, go to some low law level/high tech level world, purchase black/grey market military hardware.
Strap into your battle dress, arm your PGMP, (or FGMP if you don't care if it fills the vicinity with lethal radiation) and stomp bitches with your big ass anti-vehicle gun while you laugh at their puny bullets.
Just watch out for rocket launchers and stuff, though, and be aware you're basically wearing a tank and most governments will not be cool with you just walking around and going to bars in that thing.
Pic related, some local planetary forces up against an Imperial Marine in battle dress.

Yeah, I believe it's from Megatraveller, which would be about 1986-1991 or so. Traveller was very popular back in the 80s, so it wouldn't surprise me if some Bungee guys played it.
